KM Manual Clamping System
KM Manual Clamping Unit • Disassembly Procedures
1. Remove the two socket-head cap screws that retain the bump-off pin
(see Frame 1).
2. Grip the exposed end of the bump-off pin with pliers and pull straight out.
Some resistance may be felt due to the O-ring seal around the bump-off pin
(see Frame 2).
3. Using the appropriate metric hex wrench, remove the torque screw.
The lockrod should come out with the torque screw. Separate the torque
screw from the lockrod, remembering the lockrod has left-hand threads
(see Frame 3 on next page).
4. Remove the locking balls from within the canister. Grease can cause them
to stick inside. Pushing the balls one at a time towards the center of the
canister then turning the clamping unit upside down and tapping it against
your palm will usually dislodge them. If you must hit the clamping unit harder,
be certain you do not damage the gage or locking face of the unit. A small
magnetic screwdriver also works well (see Frame 4 on next page).
5. Normally, no further disassembly should be attempted. If the clamping unit
body or canister has been damaged, it should be replaced with a new unit.
You can also contact your Kennametal Sales office for instructions on how
to send the unit to a Kennametal Repair facility.
